Abstract (en)
[origin: EP4027013A1] Provided is a crankshaft (100), including: a first shaft (110), a second shaft (130), a first crank arm (120), a second crank arm (140), and a recessed portion (121). The first crank arm (120) is disposed at one end of the first shaft (110) and has a first oil channel (111) provided therein, and the first oil channel (111) penetrates through the first shaft (110); the second crank arm (140) is disposed at one end of the second shaft (130) and has a second oil channel (131) provided therein, and the second oil channel (131) penetrates through the second shaft (130); and the recessed portion (121) is disposed on an end surface of the first crank arm (120) facing away from the first shaft (110) or on an end surface of the second crank arm (140) facing away from the second shaft (130), and the second crank arm (140) is configured to be connected to the first crank arm (120) in such a manner that the first oil channel (111) and the second oil channel (131) are in communication with each other via the recessed portion (121). The recessed portion (121) stores lubricating oil and supplies the oil to the second oil channel (131), which improves the oil supply effect. The relative positions of the second shaft (130) and the first shaft (110) can be adjusted according to an actual displacement requirement of a compressor so as to adjust the eccentricity, such that the crankshaft can adapt to displacement requirements of different compressors and the manufacture thereof is easy. The present disclosure also relates to a compressor including the crankshaft and a refrigeration device including the compressor.
